# Oncoplastic Breast-Conserving Surgery Outcomes in the Hispanic Population at a Large County Hospital

## TL;DR

This study found that oncoplastic breast-conserving surgery outcomes are similar for Hispanic and non-Hispanic patients at a large county hospital.

## Contribution

The study provides evidence that OBCS outcomes are comparable across Hispanic and non-Hispanic populations.

## Key findings

- Hispanic patients had lower rates of delayed wound healing compared to non-Hispanic patients.
- No significant differences were found in re-excision rates or other surgical complications between the groups.
- OBCS is shown to be a viable option for Hispanic patients undergoing breast-conserving surgery.

## Abstract

Objectives: Compared to standard breast-conserving surgery (BCS), oncoplastic breast-conserving surgery (OBCS) allows for improved tumor exposure and higher volume tissue resection. OBCS also has lower rates of tumor recurrence and need for re-resection, superior cosmetic outcomes, improved patient satisfaction, and decreased postoperative breast volume, leading to lower doses of postoperative radiotherapy. Additionally, OBCS has no difference in postoperative complications or overall survival compared to BCS. While widespread use of OBCS has increased, racial disparities continue to exist in the utilization of OBCS, and there is little research investigating how race affects OBCS outcomes. To that end, our study aimed to compare outcomes between Hispanic and non-Hispanic patients undergoing OBCS at a large county hospital.

Methods: A retrospective review was performed of adult patients who underwent OBCS at a county hospital in Southern California. Subjects were divided into Hispanic and non-Hispanic groups, and the primary outcomes included the need for re-excision, hematoma or seroma formation, wound infection, areolar loss, skin necrosis, and delayed wound healing.

Results: The Hispanic group had a lower rate of delayed wound healing (p=0.022). Otherwise, there were no significant differences in demographics or outcomes between the two populations, including the need for re-excision, hematoma or seroma formation, wound infection, areolar loss, and skin necrosis.

Conclusion: OBCS is a valuable option when considering reconstruction for lumpectomy in Hispanic populations. The benefits of OBCS should not be understated and should be considered for all patients who are appropriate candidates.
